PeopleSoft General Ledger holds for the financial accounting of Northwestern Mutuals. The core tables of PeopleSoft GL has got millions data which was growing dramatically day. The historic data which was kept in the databases were causing performance issues and was no longer accessed. Data Retention was an Re-engineering project in which I have developed a new automated process for purging the historic data from the General Ledger system. I was also later on involved in General Ledger production support of the components developed.

Responsibilities:

Identify the people soft general ledger system tables for the data retention activities.

Analysis and understanding of the core business logic behind the tables identified for retention process.

Create a detailed design document on the Retention/purge process for the GL tables.

Analysis and understanding the business requirements and the Designing of the data base for the migration of the data from SQL database.

Develop the Sybase stored procedures with the Business logic, Unix scripts for executing the procedures.

Create test cases to test the Retention/Purge process for the tables identified.

Execute the test cases and validate the results to make sure that the intended records were purged and all the business logic was applied when the data was purged.

Perform the testing in multiple test databases ensure the smooth flow of the process.

Implementation activities of the components created and validate the results after the first run.

The investigations MS Access application is being revamped to new Web based application and along with this, a more reliable and stable database was designed in DB2.Investigation data migration is an end-to-end project which mainly focus on the migration of existing data to DB2 database and thus provides a smooth running of the new web based investigations application. Investigation –Data migration project involves solution modelling, designing, build, testing of build code and implementation of solution. Project is employing iterative model to implement the solution, so the project is implemented through multiple release.

Responsibilities:

Identify the tables for migration required for providing the data for the new web based application.

Analysis and understanding the business requirements and the Designing of the data base for the migration of the data from SQL database.

Understand the existing SQL database structure and get the bad data corrected.

Create the SSIS data mappings to perform the data migration from SQL data base to the new data base designed in DB2 which is a onetime built migration process.

Create test cases to ensure the Data integrity, data correctness and the record count of the data migrated.

Assist the QA team to perform the testing of the migrated data.

Performance tuning of the SSIS mappings to improve the through put.

Production Support which includes the correction of the data that has been migrated according to the application needs.
